Abstract

PROBLEM TO BE SOLVED: To send the content of a response message to a specific person by sending the response message when telephone numbers are coincident and a prescribed command is sent. SOLUTION: When a calling signal detecting circuit 11 detects a calling signal, a modem signal through an AC connecting part is demodulated by a modem processor 14 and when a telephone number is included, the telephone number is stored in an RAM 7. When the stored telephone number is coincident with a registered telephone number registered in advance as the result of comparing, a relay 9 is closed and a previously recorded response message for asking an opposite party to send a pass code is read from the response message storing part of a DSP 15 and sent to a line L. Next a sent command is detected by the tone detection part of the processor 14 and when it is a previously designated pass code stored in the RAM 7, the DSP 15 reads the recorded response message from a response message storing part and converts it to a voice signal by a read voice signal converting part to send.

Reference numeral 15 denotes a DSP (Digital Signal Processor) comprising a response message storage unit for storing a response message input from a microphone, an audio signal conversion unit for converting the stored response message into an audio signal and sending the signal to a line. ). The DSP has an answering machine function.

In such a configuration, input of a response message will be described with reference to FIG. First, the operator inputs a telephone number from the key operation unit and stores it in the telephone number storage unit of the RAM 7 (S21). Subsequently, the answer phone key is pressed (S22). Then, a response message is input from the microphone (S23), and when the input is completed (S24), the response message is stored in the response message storage unit of the DSP 15 in association with the telephone number (S25). Next, when a passcode is input (S26), the passcode is stored in the RAM 7 in association with the recorded response message (S27).
That is, the response message is stored in the response message storage unit in association with the telephone number and the passcode. If the passcode is not input (S26), the response message is stored in the response message storage unit in association with only the telephone number.

The operation of the present invention when the response message is stored in association with the telephone number and the pass code as described above will be described with reference to FIGS. FIG. 2 is a flow chart showing the processing when the facsimile machine receives a call from the other party.

First, the presence or absence of a call signal on the line shown in FIG. 5 is determined (S1). When the call signal is detected by the call signal detection circuit 11, the signal passes through an AC coupling section composed of a capacitor and a resistor. The incoming 1200 bps modem signal is demodulated by the modem processor 14 to determine whether there is a telephone number (S2). If the telephone number is included, the telephone number is stored in the RAM 7 (S3).
The stored telephone number is compared with a registered telephone number registered in advance, and if they match (S4), the relay 9 is closed (S5).
A pre-recorded response message to the effect that the other party transmits a passcode is read from the response message storage unit of the DSP 15 and transmitted to the line L (S6). The above message is, for example, a message such as "Please send a specified command."

Next, the transmitted command is detected by the tone detector of the modem processor 14 (S7), and the RA
In the case of a pre-specified passcode stored in M7, for example, "# 21", "# 21" indicates a passcode given to a specific person, and the DSP 15 transmits a recorded response message. It is read from the response message storage unit, converted into an audio signal by the audio signal conversion unit, and transmitted (S8).
Therefore, only a specific person who knows the passcode can hear an important message without anyone knowing it.

Then, it is determined whether or not the transmission of the response message has been completed (S9). If the transmission has not been completed, the response message is transmitted until the transmission is completed. When the transmission of the response message is completed, a normal response message, for example, a message such as "Please say a message after a beep."
Read out from the response message storage unit (S1)
1) Recording is started (S12). If it is a facsimile reception (S13), the recording is stopped (S14), and normal reception is performed (S15). If the fax is not received (S13), the recording is stopped after the recording is completed (S16). On the other hand, in S7, "# 2
When a command other than "1" is transmitted, the above-described normal response message is transmitted (S11), and the above operation is performed (S12 to S16). When there is no telephone number (S2), or If the detected telephone number does not match the registration number (S4), the relay 9 is closed (S10), the normal response message is sent (S11), and the above operation is executed (S12 to S16).

FIG. 4 shows a flowchart for confirming the contents of the recorded response message. First, it is determined whether or not the reproduction key of the key operation unit has been pressed (S31), and if it has been pressed, a passcode is input (S32). The response message is read from the response message storage unit of the DSP 15 based on the pass code, and the response message recorded from the speaker 16 is output as a voice (S33).
As a result, the contents of the response message can be confirmed.

[0021]

As described above, according to the first aspect of the present invention, since a response is made only from a specific partner, a response message important to other users using the same communication terminal device such as a telephone. The secret is kept without being heard.
According to the second and third aspects of the present invention, if the telephone numbers to be transmitted do not match or a specific passcode is not transmitted, "Please say your business after the beep." Or the like, and the call is not suddenly cut off, so that an appropriate countermeasure can be taken without giving any discomfort to the other party.
